Abstract: The smart walking stick helps the blind people to perform navigation and to do their work easily and comfortably. In normal stick, the detection of the obstacle is not done and normal stick is not efficient for visually impaired person, because the blind person does not know what type of things or what type of the objects come in front of them. The person cannot recognize what is the size of that object and how far it is from the object. It is difficult for the blind person to move here and there. In smart walking stick, ultrasonic sensor is used to detect the obstacle. When the obstacle becomes detected camera becomes on and the object is detected with the help of a camera. If any obstacle comes in front of blind person, they can know about the obstacle by hearing the sound generated by the microphone. This is implemented using Rasp Berry Pi 3 Model B.LDR sensor is used to detect the brightness of the environment ie to detect whether the environment is bright or dark. The system is very useful for people who are visually impaired and are often need help from others.
